(a) (i) In first 4 minutes Mary's speed was 600 / 4 = 150 m / minute

(ii) in last 4 minutes her speed was (1000-600) / 4 = 400/4 = 100 m/min

(b) Marys average speed for the whole journey = 1000/8 = 125 m/min

(d) Peter arrived at school after 7 minutes . Mary took 8 minutes. Peter first.

(e) Where they met is given by where the 2 curves intersect. That is at time 6.8 minutes and 880 m from Mary's home

(f) At t= 4 dsitance between then is 600 - 400 = 200 m

Given the conversion factor 12 in/ 1 ft, which has the larger volume?

dsp73

Answer:

A. Cube A

Given:

Cube A volume = 5832 in³

For Cube B dimension in inches:

1.2 feet = 14.4 in

1 feet = 12 in

1 feet = 12 in

So Volume of Cube B:

L × B × H = 14.4 × 12 × 12 = 2073.6 in³

Cube A has a larger volume that Cube B.

Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.

Over [174]

Answer:

y = $8(-\frac{1}{2})^x$

Step-by-step explanation:

Let the equation of the exponential function is,

y = a(b)ˣ

Since the graph of this function passes through two points $(4, \frac{1}{2})$ and (3, -1)

For the point $(4, \frac{1}{2})$ ,

$\frac{1}{2}=a(b)^4$ ---------(1)

For second point (3, -1),

-1 = a(b)³ ---------(2)

Divide equation (2) by equation (1),

$\frac{\frac{1}{2}}{-1}$ = $\frac{a(b)^4}{a(b)^3}$

$-\frac{1}{2}=b^{(4-3)}$

$-\frac{1}{2}=b$

From equation (2)

-1 = $a(-\frac{1}{2})^3$

-1 = $-\frac{1}{8}a$

a = 8

Therefore, equation of the exponential function will be,

y = $8(-\frac{1}{2})^x$

Plug the points into the equation.
Ex. y=3x-5
(X,y)
1. (5,10): 10=3(5)-5
15-5=10; point 1 is valid
-1=3(-2)-5
-1=-6-5
-1 does not equal -11
Point 2 is not valid
Same process for letter B

At the Hula Factory, the assembly line produces 212 leis in a batch. The leis are packaged in boxes with 30 each. If 14 batches

nikklg [1K]

Answer:

197 leis left over

Step-by-step explanation:

14 times 212 = 2968

2968/30 = 98.93

212 times 0.93 = 197

98 packages and 197 leis left over
